Sound issues - Fedora9 Toshiba Portege M500 with the Intel 82801G (ICH7 Family) HD AC


Hi,

I am a newbie to Linux and I have recently installed Fedora 9 on my Toshiba Portege M500 laptop with Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller. I have "2.6.25.14-108.fc9.i686" kernel.

Issues:
1. No sound coming out from internal speakers
2. When I connect headphone, I could hear a very feeble voice

What I did so far:
1. I searched internet and found a number of suggestions closely related to this. The one which matched most of my issues was the post from a280931 with title "Sound Works!" in :
http://www.linuxforums.org/forum/red...-very-low.html
2. Tried going to System->Preferences->Hardware->Volume Control and Sounds and tried all the possible combinations and a number of reboots.
3. Installed a lot of things (which I don't remember what all!) using "yum" as per directions in some other links!

Output: I still cant hear any sound from my laptop.

I would really appreciate it, if somebody could throw some lights on what else can I do!

Please let me know, if you need any other info.

Thanks!

Is alsa demon running? If not start it fom Yum, if yes restart it.
Check also, if it is run at startup (in /etc/rc.<your runlevel>, should be file called S05alsa or similar).

regards

I checked "ps -aux | grep alsa" and could not find anything. Also, I could not find any alsa related init scripts in /etc/rc3.d/...

What am I missing?

In Yum there is option called system services control
or similar, i don't remember exact name. There You can
start and stop demons which control system services.
alsa is system service. start it and You probably get the sound.
Also there is a checkbox to control start of the demon at system
startup. It should be checked.

First check mixer: kmix/alsa-mixer...or whatever

Install it if it is not there.

If you still have problems post the audio part of

#lspci -vvv

For services you do:

#system-config-services

Remove non essential services from all runlevels.

KDE or Gnome?

I did make sure that salsasound is running at startup. In system-config-services I could see it "enabled" and "running".

I tried in both Gnome and KDE. Tried almost all the settings in both kmix/alsa-mixer.

Please find below the lspci -vvv output:

Sound is back! - Thank you :)

I did not do anything after following the steps mentioned in the previous comments. I had done a reboot after that which did not fix the problem. However, after a few switches btw kde/gnome and a boot to windows gave me the sound

I believe it should have been some issue with the salsa daemon running...

Thanks a lot, all of you!!!
